Title: Motor
Inventor: KIMURA TSUNEO
IPC: H02P1/42
Filed: 1978-09-07
Abstract: PURPOSE: To increase the starting torque of a motor even at low speed operating time to enable very low speed operation by providing reactor coil in the same phase with a main coil 1 and connecting it to the tap of an auxiliary coil at low speed operating time in series with an auxiliary coil.  
     CONSTITUTION: This motor consists of a main coil M, auxiliary coils A1, A2, A3+A4, speed shifting taps 5∼8, a capacitor 10, a power terminal 9 and an reactor 10. The reactor 10 is contained in phase with the main coil M and forms a tap 7 at one end thereof and a tap 8 at the other. Accordingly, when the taps 5∼7 are switched, motor's torque is sequentially reduced to decelerate the rotating speed. When switched to a power tap 8, the coils A2, A1 and the reactor coil 10 become in series with the main coil M to allow sufficient starting torque even at low speed operating time.

Title: Refrigerator
Inventor: YASUKAWA YUKIO
IPC: F25B9/14
Filed: 1988-05-06
Abstract: PURPOSE:To increase the refrigerating capacity, by placing a pair of magnets in a high temperature chamber with their magnetic poles facing each other so as to align the magnetic ray with the axis of an expansion cylinder, and attaching one of the magnets to the lower end of a displacer and the other to a casing. CONSTITUTION:A pair of magnets 19 and 20 is placed in a high temperature chamber 15 of an expander 2 with their magnetic poles facing each other so as to align the magnetic ray with the axis of a cylinder 10. The magnet 19 among the magnets 19 and 20 is attached to the lower end of a displacer 13 and the magnet 20 to a casing 9. As a result, during reciprocating stroke of the displacer 13 from the lower dead point to the middle point, or the upper dead point to the middle point, the restoring force caused by a coil spring 11 is reduced due to the action of the magnets 19 and 20. Thereby, the displacement of the displacer 13 with time is shifted from a sine wave shape causing an increase in the total work amount of coolant gas in the expansion chamber 17, so that the refrigerating capacity of a refrigerator can be increased.

Title: Pipe with deformed cross section
Inventor: YOSHIDA KYO
IPC: F16L9/02
Filed: 1997-04-11
Abstract: PROBLEM TO BE SOLVED: To enable a pipe to be shaped so that its wall thickness is made as small as possible and that it enhances withstand load strength. SOLUTION: A pipe with a circular cross section is passed through a roll molding machine, and the two opposite surfaces 12A, 12B of a rectangular cross section are both curved into crank shapes as the clearance between them is held constant.

If so, at an underlay feed mechanism D, an underlay member is picked out by a chuck part D-2 from a stock part D-1 and placed on the bottom plate along the Y-axis direction. Next, at a core feed mechanism E, cores taken in and lined up in the Y-axis direction are chucked out of a carrying-in part E-1 and transferred onto the underlay member by a chuck part E-2 in a superposing manner. When superposition of the specified stage is over, the delivery mechanism A is driven to run and led into the next process. With this constitution, a core accumulation conveying processis made into a continuous automated process which is conducible to the promotion of labor- saving and efficiency in the manufacture.

Title: Biometallic material
Inventor: HIGASHINAKAGAHA EMIKO
IPC: C22C21/00
Filed: 1981-07-17
Abstract: PURPOSE:To obtain a composite material having high compatibility with a living body and superior mechanical properties by combining >=1 kind of metal selected from Al, Sn, Zr and Au with >=1 kind of material selected from oxide powder, nitride powder, whiskers, boron filaments and plastics. CONSTITUTION:The elastic modulus of each of Al, Sn, Zr and Au is several times that of a bone and is relatively close to that of bone. When the metals are used as a reinforcing material, a gap is hardly formed on the interface between the material and a bone, and the necrosis of the bone cells and the formation of a tumor due to the concentration of local stress are prevented. The metals have superior corrosion resistance in oxidizing environment, yet the mechanical properties are inferiro. To strengthen the metals they are combined with powder of an oxide such as calcium oxide, alumina or silica, nitride powder, single crystal whiskers or boron filaments for composite reinforcement.

Filed: 1978-09-09
Abstract: PURPOSE:To obtain a dot printer which has a common driving source and can avoid unnecessary ribbon feed operations by feeding an ink ribbon between a printing base and pressing heads linking with the reciprocating motions of a carriage in the printing direction. CONSTITUTION:One spool holder 15a is driven to a ribbon winding direction by a pulse motor 10, which is a carrier driving means, and an ink ribbon 18 is fed intermittently to the left as shown in the figure linked with the movement of a carrier 4. therefore, there is no need to provide a driving source to feed the ink ribbon 18 and the construction is simplified. As the ribbon is fed by the carrier driving means, the ribbon is fed only when the carrier is moved, and so unnecessary ribbon feed is avoided and the ribbon feed is stopped while a wire dot heat 6 is in contact with a printing base 2, therefore, the lift of the ink ribbon 18 is increased.
